Improved horizontal water-wheel



UNITED STATES PATENT OEEICE.

ABRAHAM ANDRElVS AND HARRISON KALBACH, OF BERNVILLE, PENN- SYLVANIA.

IMPROV'ED HORIZONTAL WATER-WHEEL.

Speciiication forming part of Letters Patent No. 25,237, dated August 30, 1859.

To all whom t may concern,.-

Be it known that we, ABRAHAM ANDREWS and HARRISON KALBACH, of Bernvlle, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Tater-Wheels; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompnying drawings, in which Figure l represents a perspective view of said water-wheel, and Fig. 2 represents a perspective View of the stationary guide-wheel, through which the water passes before it reaches the water-wheel. Fig. 3 represents a bottom view of the water-wheel. Fig. A represents a vertical central section through the entire apparatus.

The nat-ure of our invention relates to the peculiar construction of the buckets of a horizontal waterwheel, by means of which a greater effect of the water is obtained than in wheels used heretofore, and in connection with the manner of incasing the wheel.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

A represents a rectangular box which is closed at the top and sides and open only at the bottom. The water-wheel is mounted within the box, which is connected in the usual manner with the iiume of the waterworks.

B represents a frame-work, which is secured to two opposite sides of the box A in such a manner as to leave a space R between it and the two other sides of the box A, through which the waste water is to escape.

D represents the spiral water-way or inlet, which is secured within the frame B. The shape of this inlet or water-way is represented at Fig. 2. It consists, substantially, in a helixshaped conduit D, which is secured between the inner cylinder M and the outer cylinder N, and the inclination of said conduitis such as to cause the waterto strike the buckets of the wheel in a direction which will result in the greatest possible eect of the Water.

O represents the water-Wheel. Itis secured to the hub G, the pivot E of which runs in the step a of the cylinder M. Thebuckets of the Wheel are of such a shape as to present a concave surface to the action of every particle of water which strikes them. In this way it is believed that the water will act on every point of the bucket in a perpendicular direction, and therefore exert a greaterpressure on the same than when impinging thereon in an oblique direction. The shape ot' the buckets will be Seen by the drawings. The lower edge K of the same is a curve and the bucket P itself is also curved in its longitudinal direction. Therefore every element of the bucket must be of a curved shape, as above described.

The operation of our water-wheel is as follows: The water enters the spiral inlet D through the inlet H and passes up theincline D, where it is guided to strike the buckets of the water wheel in the proper direction, where it acts upon said buckets in the manner above described, causing the wheel to rotate on its shaft F, and thence escaping' from the buckets at their upper edges L, and thence through the space R down into the waste-water fiume. The tops as well as the bottoms of the buckets are curved or eccentric, and not radial, as usually made, and d fer in this particular from the Wheel patented to Abraham Andrews, one of the parties` to this Application, on the lst of March, 1859. The draft-box wheel and its several appliances are arranged within the forebay S, which is open at top, as shown in Fig. et, said forebay being of any of the ordinary forms of construction.

Having thus fully described the nature of ourinvention, what We claim therein as new, and desire to secure by Letters Patent, is-

The curved concave buckets having curved or 'eccentrically-forined tops and bottoms, in combination with a spiral water-way or chamber underneath and arranged within a box A, substantially as herein described and represented.
